Description

The TLC5940is a 16 channel PWM unit with 12 bit duty cycle control(0-4095), 6 bit current limit control (0-63), and a daisy chainableserial interface. This breakout board is a good way to take
fulladvantage of this useful IC. All 16 PWM channels are broken out tostandard 0.1" headers, which run alongside convenient voltage andground rails. Also, because the TLC5940 can be daisy-chained, thebreakout is designed to support that feature. On the left-hand side ofthe board all serial inputs are broken out to 0.1" headers andlikewise with output on the right-hand side.

Use this board to increase the number of PWM pins available to yourmicrocontroller for applications such as Monocolor, Multicolor orFull-Color LED Displays, LED Signboards, Display Backlighting, Servocontrol, or any other project where a large number of PWM drivers arenecessary.

Note: While each 3-pin PWM header is 0.1" spaced, the space betweeneach header is slightly larger in order to accommodate servoconnections. In order to make this board suitable for use with servos,2.2k pull-up resistors have been included on each output as well.Finally, the 2.2k resistor on the Iref pin sets the output current to17.8mA but a parallel through-hole connection is provided for anadditional resistor to increase the current if necessary. To determinethe resistor value you need for a given output check the equationsprovided on the schematic.
